Purpose: The aim of this study was to examine: (1) motivations of patients with chronic low back pain to attend physical therapy; (2) relationships between competence perceptions, motivational regulations, and pain/disability; and (3) whether patient motivations to attend physical therapy mediate the relationship between competence perceptions and pain/disability. Methods: A sample of 64 participants completed baseline assessment (1-week prior to initiation of physical therapy) and 6-week follow-up assessment. Differences between motivation variables at baseline were examined using one-way within-person ANOVA. Relationships between competence perceptions, motivation subscales, and pain/disability were calculated using bivariate correlations and multiple mediation analyses. Results: Participants reported significantly higher levels of autonomous versus controlled motivation (mean difference = 3.5, p <0.001, d = 2.3) and amotivation (mean difference = 3.6, p <0.001, d = 2.4). Competence was positively associated with autonomous motivation (r = 0.45, p
